Well, I've cooked on it three times now. I grilled a pork roast, made pizza and smoked some ribs.
The ceramic mass makes it very fuel efficient and the temperature control is outstanding. I still can't get used to shutting down the exhaust vent to control heat, but it is really necessary. Temperature is very responsive, too. Once you move a vent, you can watch the needle on the thermometer move right away.
As a grill it excels. No wasted heat and it gave the pork roast a nice dark brown bark while the inside was tender and juicy. I ran it at about 350 deg. F.
I screwed up the pizza because I didn't understand how to control the temperature. The stone was too cool for the first pie. Once I figured out the vents though, I could easily maintain temperatures exceeding 700 degrees F (the thermometer only goes to about 550 F - way too low IMHO. I may have to see about getting a different thermometer.
While smoking the ribs, the temperature control was outstanding. I was easily able to keep it at 225 - 250 deg F for five hours. Again the meat had a nice dark brown bark and was tender and juicy inside. I left the ribs on a tad too long, but they weren't all dry and crusty, nor falling off the bone. I liked the texture it gave them. You can't use very much wood in them though. With so little air movement, it is really easy to oversmoke things. Fortunately I knew that going in.
My only complaint is the size. I've come to love the 22.5" WSM and the grate on this one is 18". I had to roll up my ribs to fit the two racks and the tips on the grate. I prefer cooking my ribs flat - which the large WSM allows. So if you are just smoking one piece of meat (a brisket or a pork butt) I'm sure it would be fine, but I tend to smoke a lot of stuff when I smoke, so I will probably use the WSM or my competition offset for that task.
Post some reviews if you get a chance. My WSM is a bit old an I was considering one of these BGE knock offs since the prices is a lot more affordable just not sure if i'm going to get the same results as I love my WSM.
